1 Claim.

The invention'relates to a roofing and more especially to a permanent roofing construction.

The primary object of the invention is the pro- Vision of a roofing of this character, wherein the appearance thereof gives a tiling effect yet the same is made from wire mesh fabric, one fabric being of a fine mesh character and the other being of a coarse mesh character, these being corrugated in superimposed relation to each other and entirely covering the outermost fabric is a cementitious body, the roofing being permanent in character and is protective against water seepage to the interior of an edifice and will withstand climatic changes.

Another object of the invention is the provision of a roong of this character, wherein the make-up of the same is novel in its entirety and assures maximum life quality, being easily set up for coverage of an edice at the roof thereof.

A further object of the invention is the prol,

vision of a roong of this character, wherein air spaces will be created therein and is thoroughly weatherproof.

A still further object of the invention is the provision of a roofing of this character, which is simple in its construction, thoroughly reliable and efficient in operation, neat and attractive in appearance, giving tile effect, durable with assurance of maximum life, readily and easily applied and inexpensive to manufacture.

With these and other objects in View, the invention consists in the features of construction, combination and arrangement of parts as will be hereinafter more fully described, illustrated in the accompanying drawing, which discloses the preferred embodiment of the invention and pointed out in the claim hereunto appended.

In the accompanying drawing:

Figure 1 is an elevation of a roofing partly in section constructed in accordance with the invention.

Figure 2 is a sectional View on the line 2-2 of YFigure 1.

Figure 3 is a sectional view on the line 3-3 of FigureV 1.

Figure 4 is a vertical transverse sectional View through the ridge of the roofing.

Figure 5 is a fragmentary bottom plan view of the eaves area of an edice or roof. g

Similar reference characters indicate corresponding parts throughout the several views in the drawing.

Referring to the drawing in detail, A designates generally a portion of a roof sheathing common (Cl. 10S- 1) in the building of roofs and in this instance is a part of a ridge roof for an edifice.

Built upon the sheathing A is a roofing construction constituting the present invention and comprises an innermost fine mesh metal fabric I and an outermost relatively wide open mesh metal lathing lt, respectively, these being in sheet formation and are superposed one upon the other for overlying the sheathing A at opposite sides of the ridge built thereto. These sections if) and II are outwardly struck at intervals for effecting a corrugation trend I2 therein and producing separated air cells or spaces I3 next to the sheathing A, the corrugation I2 being transversely to the longitudinal lay of the roofing and terminates removed from the uppermost edges of the sections I0 and II next to the ridge of said roof while related to this corrugation trend I2 in the hollows I4 thereof having contact with the sheathing A at selected points thereof are fasteners I which are driven through the sections I0 and li and into the sheathing A for the fastening or securing of these sections in place.

At the ridge is arranged with respect to the sheathing A a ridge unit, being formed from the fine wire mesh fabric I6 and the open mesh lathing Il, respectively, shaped in their superimposed relation to each other into partially circular formation while the edges of these sections I and I'I are brought together throughout the longitudinal extent of the ridge piece and are laterally flared to be reversely angled to the vertical for creating overlapping anges I8, which are carried over the edges adjacent thereto of the assembled sections I0 and I I, being fastened in place by fasteners I9 driven into the sheathing A.

Overlying the lathing sections II and Il is a cementitious covering body 20, being delivered through the interstices of the said lathing sections II and Il for the interlocking of the body therewith while the wire mesh fabric sections IG and I6 are a backing for checking the inward working of the body 2t when the cementitious substance is being applied for the coating and coverage of the lathing sections il and Il, respectively, with resultant assurance of the locking of the cementitious substance with the lathing sections. This cementitious body 20 may carry coloring matter for decorative purposes and giving attractive finish to the permanent roofmg.

At the eaves edge of the roof sheathing A is arranged a sealing section to the air spaces I3 and comprises the innermost ne mesh metal fabric 2I and an outermost relatively wide open mesh metal lathing 22, respectively, the latter being locked with and covered by the cementitious body 2li, which is outermost thereto. These sections 2| and 22 are fastened to the eaves edge by suitable fasteners, one being denoted at 23. The sections 2| and 22 are cut at their outermost edges in a iiuted fashion for matching the corrugation trend I2 and meet the edges adjacent thereto, which are the lowermost edges of the sections IIJ and Il and in this manner a permanent roof construction is had.

What is claimed is:

A roofing construction comprising sheet-like lowermost ne and uppermost coarse mesh metal fabrics superimposed one upon the other for overlying roof sheathing at opposite sides of a ridge built therewith, a partially cylindrical ridge unit having lowermost fine and uppermost coarse woven mesh metal sections superimposed one upon the other and arranged at said ridge for saddling the latter and in overlapping relation to the first-mentioned fabrics, a cementitious covering associated With the rstand last-named fabrics and interlocked with the coarse mesh fabrics thereof, corrugations formed in the first-mentioned fabrics and disposed at right angles to the ridge unit, the first-mentioned fabrics being extended downwardly from the ridge and underturned at the eave for sealing the spaces between the corrugations and roof sheathing, and means concealed by the cementitious covering and securing the said fabrics to the sheathing.
